"The best thing to be done," said Roper, quietly, "is to find out some one who knew Verschoyle."
"Yes, but how can you find out such a person?"
"I have done so!"
"Already?"
"Yes; he has a sister staying in London, and I know where to find her."
"Indeed."
"Yes; she is a Mrs. Taunton, and her husband is at artist; if we could see her and get her to show Mr. Monteith a portrait of the deceased, he would be able to recognise it."
"Of course I should," said Ronald, eagerly.
"Then," pursued Mr. Roper, without altering his voice; "there is another bit of evidence we must get hold of; the letter sent by the wife to Verschoyle, saying she would kill him."
"But how can we obtain that?"
